"Why is he talking about my players? It’s not the game," Holloway told The Sun.

"I will be picking the phone up to talk to him as I don’t think it is right and proper with the greatest respect. That is totally bad etiquette."

With the Eagles currently second in the Championship, a point behind league leaders Cardiff City, Holloway maintains that the 20-year-old forward has a key role still left to play in their promotion push this term, dismissing the suggestion that the club would consider selling him in January as a result.

He added: "Wilf is a big part of our season - and we have such a strong contract others can go and whistle. He won’t be available, no matter what the price is, in January."
